Also, look for HUD homes with a website that ends in (or has in the middle) .gov . I tried it but either the site is down or my computer is acting up.
Those are all the free official government websites. You will have to narrow down the search by state and city.
That or have a real estate agent do it for you.
If you are thinking about purchasing a foreclosure home, please contact me. My cell number is listed below. I have access to all of the foreclosures in the Las Vegas valley. You can pick up some really nice foreclosure homes at a great deal right now too. Also, my service and representation for buyers is completely free. Hope to speak with you soon.
